It's a rolling coffee table. No, it's a rolling ottoman. No, it's a rolling stool. Actually, it's any of those three things...or all of them. Just call it the Cube, a jaunty little piece that comes in six colors and three sizes. Oddly enough, the XL size (24" x 24" x 24") is the most expensive but the only one without wheels. Oh, and when I say expensive, I mean it. The XL version will run you $3,900!
